100 THE TRIAS OR NEW RED SANDSTONE. 



notes the following memoranda of the appearances. On the south 

 side of the river, near the bridge, there are gray and brown shales, 

 red sandstone, red grit, and conglomerate, with high dips and dis- 

 turbed. These are evidently Lower Carboniferous, and quite different 

 from the horizontal soft red sandstones which appear lower down on 

 the same bank. On the north side, at the end of the bridge, are dark 

 red grit and conglomerate, grayish conglomerate, marly and shaly 

 beds with gray calcareous concretions, and a vein of calcareous spar. 

 They dip N.E. and N.N.E. 38°. The limestone and gypsum seen a 

 little below the bridge are associated with these beds, the whole 

 being Lower Carboniferous, as indicated by the fossils of the 

 limestone. In the road-cutting, soft red sandstone and conglomerate 

 overlie these beds, and though they have a steep false bedding, I 

 believe they are New Red and unconformable. In the same road- 

 cuttings, these upper beds are seen to be made up of the debris of 

 the lower, with which they are confusedly intermixed at their confines, 

 the underlying marls in some places rising like veins into the sand- 

 stone above. At Folly River the New Red is soft and fine grained, 

 with greenish stains and layers, and has a very slight northerly dip. 

 In the point opposite the village, sandstones, apparently the continu- 

 ation of the older formation seen at the bridge, dip to the N.E. at a 

 very high angle. 



Within this islet of Lower Carboniferous rock, the New Red Sand- 

 stone extends up the Folly River, which runs into the same estuary 

 with the De Bert, for about five miles. Its dip increases until it 

 amounts to 50°, and the lowest beds rest against the disturbed Car- 

 boniferous rocks which occupy the bed of the river between this 

 place and the base of the Cobequid Mountains. Near their junction 

 with the older rocks, the red sandstones become coarse and pebbly. 



Westward of Folly River, the belt of red sandstone gradually 

 decreases in width, and begins to contain in its lower part thick beds 

 of conglomerate, made up of pebbles derived from the older rocks to 

 the northward. Near Portapique River, and someAvhat removed from 

 the coast, there is an eminence that I have not visited, but I was 

 informed by a gentleman, very familiar with this part of the country, 

 that it consists of trap. If so, this is the first appearance of that rock 

 in this direction. 



The new road along the bank of Great Village River, between that 

 village and the Acadian iron mine, exhibits an interesting section of 

 this formation, consisting of red sandstones and red conglomerates 

 with imperfectly rounded pebbles, and often with oblique or false 

 bedding. They often rise into cliffs of considerable height, and have
